Dear All, I have a question. <Pre-study, 1*2, Crossover design.> When calculating Intra CV, is there a case of 0? What should I do in such case? Edit: Category changed; see also this post #1. [Helmut] |

Hi youivab, Unclear question. Are you talking about already done study? |

❝ intra CV zero!!! ❝ Are you dealing with man or machine?!! which have also a little precision... I used SAS program. This is the code I used. ODS OUTPUT COVPARMS=RESIDUAL8; Edit: Full quote removed. Please delete everything from the text of the original poster which is not necessary in understanding your answer. Tabulators changed to spaces and BBcoded; see also this post #5 and #6. [Helmut] |

I think, because of random effect in the model, the inter CV is zero. Regards, GM — Best Regards, GM |
